UNITED STATES PATENT OFFICEI FEED DEVICE Edwin T. Lorig, Gary, Ind.,assignor to American i Sheet and Tin Plate Company, a corporation of NewJersey Application October 9, 1933, Serial No. 692,897 Renewed (Dctoberl., 1937 3 Claims.

rial the product is very difficult tov handle forV the reason that it isusually at least two hundred feet in length, more than 36 vinchesl inwidth, is

" of relatively heavy gage (l. e. approximately 0.065 gage and heavier),and consequently weighs well over one ton. Considerable trouble isencountered in successfully feeding long material of this sort intoshearing devices, due to its cumbersome proportions, great weight, andcambered or bowed condition, and evenafter being drawn into the shearmechanism is diiiicult to maintain A in proper position to permitaccurate and square shearing or uniform processing.

' 20 One object of the present invention is the pro-` vision of a novelstrip-feeding device which 'will be cheap and easy* to manufacture andprove very durable in service.

Another object is to provide -means for intermittently releasing thestrip to be processed from.

the feed device so that it may be positioned properly in the processingmachine. without undue -mechanical interference and without delaying the,positionlngof such material by the operator.l Still another object istoprovide novel means for successfully and economically feeding camberedor bowed long and heavy strip metal in a releasable manner,thuspermitting operators to change from time to-time the position oftheadvance end of the strip in the feed device with rapidity and littleeiort. '4

These and still further objects will be apparent after referring to thedrawings, in which: Figure 1 is a pian of the apparatus of the vinvention.

Figure'z is an end elevation thereof. Figure 3 is a view on the lineIII- III of Figure1.."

Figure 4 is a view on the line -IV-IV vof Figure l;

Referring more particularly to the drawings, the letter A designatesstrip material of the class described while B is a shear or otherprocessing mechanism-to which it is to be conveyed.

A frame 2 is positioned adjacent the shear B (cl. zii- 2.3)

tional type of pliers, or other'gripping device, 1.,.

A motor 8 is disposed adjacent the frame 2 and actuates a transmissionunit 9 which has a clutch device I0 on its driven shaft for enabling themanual clutching and declutching of the 5 drive for the shaft d.

A shaft I2 is journaled in the frame 2 and carries a roller It and asprocket I5. A shaft I6 is journaledvin the frame 2 beneath the shaft I2and offset with respect thereto, and slipprts l0'l .a carriage II whichis in the form of/a bell-crank lever.-

I8 which is Aadapted to rotate in unison wit the socket I5 by means of achain I9.

The carriage or bell-crank lever I'I carries at `15- one of its ends ashaft 20 on which a roll 2-I is mounted. The shaft20 is also providedwith a gear 22 while the shaft I6 carries a gear 23 which is in constantmesh therewith.

The shaft I2 carries a gear 24 on its end 'remote fromthe sprocket I5whichis adapted for constant enmeshment with a gear 25 on the shaft il.4

'I'he carriage or bell-crank lever I'l is coni nected at the other ofits ends to a piston-rod 25 Y 26 which is associated with a conventionaltype of fluid cylinder 21. A foot control button -28 is disposedadjacent the controls for the shear B and is adapted to control the ilowof iiuid t the fluid cylinder 2l through pipes 29 v30- In operation, thepliers 1 on the end of the rope 6 aremanually carried out onto thecoolingbed way 3 whereupon its 4advanced end will move to aposition-beneath the roll Id. At this time the clutch device `II isdisengaged, and the pliers I .4c detached from the material. Theremainder of `the rope t is wound on the reel andthe pliers I are thensuitably'connected to the latter. The

clutch device I@ is again engaged. Due to the weight of the roll 2l andthe absence of fluid in et4 the fluid cylinder 2l, the bell-crank leverIl wllly have permitted the roll to move out of contactwith theronle. ,Y'Y

'Ihe shear operator steps upon the control but" ton 28 whichlcausesfluid to flow through the 5I pipes l29 andlntothe uid cylinder 2J, whichcauses the rod 2 6 to move in the'direction of the arrow in Figure 2,and thusmove the roll 2| into contact. with the bottom of the strip Aand `accordingly advance it. This causes the material 5I;

The shaft I6 is provided with a. sprocket length.

From the foregoing description it can readily be seen that the operatorcan manipulate the fluid control button 28 to vary the supply of uid tothe cylinder 21 and thus adjust the pressure of the roll 2l toward theroll I4. This feature permits the operator to utilize high pressure whenthe rolls 2| and 24 are pulling the advance end of a long and heavystrip A and to diminish the same as the trailing end approaches.

In Figure 1 of the drawings two devices of the class described are shownas being operated in conjunction with asingle wide shear, but it is`obvious that a greater or lesser number of devices of the invention maybe used with any type 4 of processing machine.

While I have shown and described one speciflc embodiment of my invention-it will be understood that I do not wish to be limited thereto, sincevariousmodications may be made without., departing from thescope-thereof, as

defined inthe appended claims.)
